From Technet :
Private queues are accessible only by Message Queuing applications
that know the full path name, the direct format name, or
the private format name of the queue, as follows:
* Path name:ComputerName\private$\QueueName.
* Path name on local computer: \private$\QueueName.
* Direct format name:: DIRECT=ComputerAddress\PRIVATE$\PrivateQueueName.
* Private format name: PRIVATE=ComputerGUID\QueueNumber.
For more information about queue names, see this article . One thing to note is that it is not possible to determine if the remote private queue is transactional or not, and if you send with the wrong transaction option, the message is discarded.
